A position detection system includes a measurement unit that obtains a measurement value related to transmission and reception of radio waves from when the radio waves are transmitted from one of first and second communication devices to the other one of the first and second communication devices to when the one of the first and second communication devices receives a response to the radio waves to detect a positional relationship of the first and second communication devices. The measurement unit obtains multiple measurement values by performing communication to obtain the measurement value a multiple number of times in which a parameter of the communication is changed.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The position detection system according to claim 1, wherein the measurement unit measures a propagation time of the radio waves as the measurement value.
5. The position detection system according to claim 1, wherein when one of the first communication device and the second communication device transmits the radio waves and the other one of the first communication device and the second communication device receives the radio waves and then transmits a response to the radio waves, the measurement unit transmits the response a multiple number of times to obtain the measurement value a multiple number of times.
